我有一个与 ArticleOrder 实体有 OneToMany 关系的 PurchaseOrder 实体。此外，ArticleOrder 实体不仅包含 Order 和 Article ID ，还包含 Amount。此外，ArticleOrder 实体与另一个名为 ArticleSupplier 的实体具有 OneToMany 关系。这样每篇文章的订购金额可以拆分给多个供应商。现在我想建立一个表格来解决这个问题。所以我创建了三种表单类型：

一个只包含 ArticleOrders 的嵌入式集合：

 public function buildForm(FormBuilderInterface $builder, array $options)
{

    $builder->add('purchaseOrders', 'collection', array('type' => new ProducedAmountOrderArticleType()));
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Acme\AppBundle\Entity\PurchaseOrder',
    ));
}

一个包含 ArticleSupplier 条目的嵌入式集合：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('articleOrderReferences', 'collection', array('type' => new ProducedAmountOrderSubArticleType()));

}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Acme\AppBundle\Entity\ArticleOrderReference',
    ));
}

还有一个用于 ArticleSupplier Amount 输入字段：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('produced');

}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Acme\AppBundle\Entity\AOSupplierReference',
    ));
}

树枝代码：

<span class="purchaseOrders">
                    {% for purchaseOrder in form.purchaseOrders %}
                        <span class="articleOrderReferences">
                            {% for articleOrderReference in form.articleOrderReferences %}
                                {{ form_errors(articleOrderReference.produced) }}
                                {{ form_widget(articleOrderReference.produced, { 'attr': {'class': 'input-mini'} }) }}
                            {% endfor %}<br>
                        </span>

                    {% endfor %}
                </span>

控制器：

           $form = $this->createForm(new ProducedAmountOrderType(), $order);

//         // process the form on POST
//         if ($request->isMethod('POST')) {
//          $form->bind($request);
//          if ($form->isValid()) {

//              $em = $this->getDoctrine()->getManager();
//              $em->persist($order);
//              $em->flush();

//              return $this->redirect($this->generateUrl('order', array('id' => $orderId )));
//          }
//         }

        return $this->render('AcmeAppBundle:ProducedAmount:index.html.twig', array(
                'form' => $form->createView(),
                'order' => $order,
                'articles' => $articles,
        ));

我评论了请求帖子，因为这只会导致空白页。现在我总是收到此错误消息：

Method "articleOrderReferences" for object "Symfony\Component\Form\FormView" does not exist in AcmeAppBundle:ProducedAmount:index.html.twig at line 150

我做错了什么？

这个：

{% for articleOrderReference in form.articleOrderReferences %}

应该：

{% for articleOrderReference in **purchaseOrder**.articleOrderReferences %}

当然去掉*。我试着让它变得大胆。
